As a leading factory and supplier in China, we offer CPF candle filters that are compatible with monomer, pre-polymer, and polymer filter systems, ensuring optimal performance in your manufacturing process
The construction of the CPF candle filter is a testament to engineering precision. At their core, is the polymer filter element, a vital part engineered to efficiently trap contaminants and impurities. These filters bear a resemblance to candles, and are crafted from high-quality materials which are capable of withstanding the extreme temperatures and pressures encountered in polymer manufacturing. Crafted from materials like sintered metal or ceramics, the polymer filter element forms the foundation of all CPF candle filters. This core houses an intricate network of channels, forming a sophisticated filtration pathway.
The term polymer candle filter signifies precision and excellence in ensuring the purity of polymer products. CPF candle filters operate as polymer melt flows through them. Along this complex path, contaminants are captured, leaving behind only the pure polymer. It's a process that guarantees the final polymer product meets the strictest quality standards.

Frequently Asked Questions
Q What is a CPF candle filter and how does it work?
A CPF candle filter is a precision filtration device used in polymer manufacturing. It works by allowing polymer melt to flow through a filter element — typically made of sintered metal or ceramics — which captures contaminants and impurities through an intricate network of internal channels, ensuring only pure polymer passes through.
Q What materials are used in the polymer filter element?
The polymer filter element is primarily made from SUS304 or 316L stainless steel. The filter media options include metal sintering mesh and stainless steel wire mesh, both of which offer excellent corrosion resistance, high temperature tolerance, and long service life.
Q What filtration ratings are available for CPF candle filters?
CPF candle filters are available in filtration ratings ranging from 1 to 200 microns, making them suitable for a wide variety of polymer melt filtration applications across different industries.
Q What is the maximum working temperature for these candle filter elements?
The candle filter elements can operate at working temperatures up to 350℃, making them well-suited for high-temperature polymer processing environments. They are also rated for a maximum allowed pressure difference of 10 bar / 14 psi.
Q How are the candle filter elements quality-tested before shipment?
Each polymer filter element undergoes bubble-point and air flow testing before shipment to verify product integrity and performance. A test certificate is provided with every lot, and all elements are laser-marked for traceability and reliable after-sales service.
Q What is the difference between stainless steel wire mesh and sintered fiber filter media?
Stainless steel wire mesh is woven from stainless steel wire and features smooth pores, easy cleaning, and a long filtration cycle. Stainless steel sintered fiber, on the other hand, is a porous deep filter material sintered at high temperature, offering higher porosity, better air permeability, stronger dirt-holding capacity, and superior regeneration ability.
